Lets mount our /dev/sdb1 disk partition with ext3 filesystem to mount point /mnt/sdb1:

mkdir /mnt/sdb1
mount -t ext3 /dev/sdb1 /mnt/sdb1

mount disk partition with ext3 filesystem
we can now use -o remount option to remount it with read only permitions only:

mount -o remount,ro /dev/sdb1 

re-mount disk partition with ext3 filesystem read-only
To mount it back with read & write permitions:

mount -o remount,rw /dev/sdb1 

re-mount disk partition with ext3 filesystem write

With mount command we can mount all kinds of filesystem. For example to mount ISO image we can do:

mount -t iso9660 myiso.iso /mnt/cdrom -o loop
